Swing Copters (free, iOS), which launched today, looks pretty dang hard. To play the game, tap to control your flight direction and avoid the swinging gates. It's the kind of game that's simple yet mystifyingly challenging (aka the kind of game we love to hate). The app is free, with a $1.29 in-app purchase to remove ads. Apparently, flying with a propeller hat is not as easy as it looks.
